    That seems to be, well, a lot of smoke from the crankcase.

    You might want to check cylinder compression yourself. Or have another mechanic check it.

    Hey... no judgement ... not hatin' ... break-in procedure??
    Hind-sight 20/20, you might have tried to take the ski out to 20-30 hrs stock, before mod'ing & WOT'ing it under 10 hours with breakin oil still in it.

    I've broken in every dirtbike/streetbike/jetski hard, and never had any issues. Age long debate, but not what this thread is about.

    Going to run a compression test this weekend and see where we're at.

    Wow that's way too much smoke, your best bet is to go to another Yamaha dealer I wouldn't be riding it the way it is

    Just did compression - Cylinder #1 150, Cylinder #2 130, Cylinder #3 65, Cylinder #4 150.

    they recommend a gum out cylinder cleaner to see if the rings r jammed up. Any recommendations?

    How many hours on this engine?

    Gummed up piston rings on a 2019 engine seems unlikely.

    Can you put a bore scope down the spark plug hole for a visual check of piston condition?

    6.2 hours. I’m going to the dealer tomorrow morning to see what the deal is, but unreal!

    I'd really like to know what caused this... If you can please follow up once the dealership gets another look at it.
